Tips and Installation Learn how to install a dehumidifier pump. From "Ed the Plumber" episode DETP-311

8. Using a low voltage alarm, put the yellow leads on the pump onto the place of the door bell described in the manufacturer's instructions.

9. Connect the leads from the pump into the alarms leads.

10. To test the alarm, make sure that the pump is not plugged in—but that the alarm is. Pour water into the condensation pump until the alarm goes off, which should be when the water reaches the top.

11. To move the water from the pump to the sump, use a clear plastic flexible hose if the length is less than 10 feet. Use PVC pipe if it's over 10 feet.

12. Use a transition fitting to connect the plastic tubing to the PVC. Glue the fitting on one side, and then a barbed fitting (figure F) on the other that will connect to the plastic tubing.

13. Wrap the threads of the barbed-to-machine threaded adapter with Teflon tape. Hand screw it into a PVC 3/4" to 1/2" threaded bushing. Use a pair of slip joint pliers to snug it down. Be sure to not over tighten.

14. Use PVC cleaner to clean the other end of the bushing and both ends of a 3/4 inch PVC coupler. When the cleaner is dry, apply PVC glue to the bushing and one end of the coupler. Be careful to keep the glue off of the barbed side of the bushing.

15. Pushing the pieces together, slightly twist them as they slide into place. Be sure to hold the two pieces together to prevent them from pushing apart. Let the fitting completely dry before connecting the plastic hose.

16. Run the PVC drain lines. Make sure the lines are pitching downward, so that gravity pulls the water down and out.

17. Drill through the wall behind the dehumidifier (figure G), and then work the hose into the hole.

18. Measure and cut the PVC sections so that the end of the pipe will be directly in the sump. This will help to avoid any spillage or splash.

19. Use 90-degree elbow's and couplers to work the PVC pipe back to the condensate pump--cleaning and gluing the connections as you go. Be sure that the line runs down hill toward the sump, and then secure the pipe with clamps (figure H).

20. When making turns on the horizontal sections of the pipe, use 45-degree elbows to make the turns gentler, this will help avoid any water hammer noise.

21. Connect the hose to the PVC adaptor at the end of the PVC.

22. Work the hose from the wall to the fitting, and then cut it to length.

23. Attach the hose to the barbed fitting (figure I) and secure it with a zip tie.

24. To test the system, make sure that both the dehumidifier and the condensate pump are plugged in to an outlet.

25. Pour a bucket of water into the system, and then check all of the plumbing joints for leaks. Also, check the sump area.
